I have been talking to Netbeans team about us adopting the project and this is a done deal. Putting together some details and you should see a blog post about this in the next few days. So, if you like using Netbeans dont worry, it will still be an available option in the plugins catalog (not sure about the full Ruby product as an independent download from netbeans site yet).

Good news for all those that would like to continue to use NetBeans with Ruby.
